    Help needed for year ten trigonometry question

    it's rising vertically. so it's a sohcahtoa question. tan 27 = x / 300 and tan 61 = y / 300 solve x and y. now, speed = distance / time so, speed = (y-x) / (7.03am - 7.00 am) you should be able to do b now.

    Poll: How would you prefer a textbook with solutions to be split?

    Option 1 sounds better. Make the solutions a 'teacher's resource' and price it high - every school will buy it, guaranteed, and some students will too. But more importantly, students won't look at the solutions at the drop of a pin, and thereby forego any thinking they may have had to do - which...

    How many case studies to excel?

    you want goods + services case studies, preferably 1 each for differentiation (eg Apple for goods + Qantas for service) and cost leadership (eg Kmart for goods + IMO car wash for service). it's important to note that you CAN use hypothetical case studies too, as long as they make sense.

    (Year 11) Where to get practice questions for MX1?

    this :-) just look at old past papers, and find questions for topics you're doing. There's also quite a few collection of questions by topics floating around on the internet which you can use, including compilation of HSC/CSSA questions by topic. for some of the newer topics, like pigeonhole...

    Best 2U resources, HARD QUESTIONS. (State Rank)

    after you finish a topic, go through ~50-100 past papers and make a collection of past paper questions which are relevant to the topic you've just finished. then go about answering them SLOWLY. Don't rush through them all on the same day. By far and away the most important thing is to make sure...

    Driving test routes - Penrith / Blacktown / Parra / wetheril park

    Is there a kind soul who could use MS Paint (or equivalent) to draw up a test route? I'm in the west side of Sydney, so preferably Penrith/blacktown/Parra/Wetheril Park. If we could make a small collection in this thread, I'm sure it would help the confidence of many people in the future...

    Help im in a crisis

    doing well in general will still require a major time committment. better to just devote time daily to 2u adv maths imo. you should only drop if you genuinely found 2u adv to be too hard, and you were struggling to understand the concepts.

    Band estimate for each question in past Mathematics HSCs

    just do up to question ~8 in old format trial papers (ie papers without multiple choice questions), and up to question ~14 or so in the newer format papers (ie ones with multiple choice). I'd say that's a "band 4" level. although, if your students can do EVERY question up to the ones I've...

    imho you haven't been taught permutations and combinations properly. the questions ARE very predictable, and you CAN learn this topic. There are specific archetypes that repeat all the time. Yes, you do have some extremely hard questions, but you can say the same for every other topic too. The...

    alternatively, divide into 3 cases: oldest woman in, youngest girl not oldest woman out, younger girl in oldest woman out, youngest girl out you get the same answer :-) just understand what you're doing and think your way through. integral's way is 100% correct too.

    Post Trials / Current Trials discussion thread for Business Studies

    if everyone uploaded their trials, I think we'd have a nice collection of practise papers for the HSC. unfortunately, our school did CSSA, and I believe it's illegal to upload CSSA papers. Having said that, the ER sections were fairly generic I felt. here are some of the noteworthy (imo)...
